Problems solved by technology

[0003] In addition, in the printer of Patent Document 1, after the inclination angle of the head unit is adjusted via the sliding member by rotation of the adjusting eccentric cam, the position of the sliding member is fixed with a fixing bolt (bolt). This keeps the inclination angle of the head unit at an appropriate angle. However, the fixing position of the sliding member by the fixing bolt is separated from the eccentric cam for adjustment.
Therefore, there is a problem that the angle of inclination of the head unit is shifted due to shifting of the fixing position by fastening of the fixing bolt.

Embodiment Construction

[0031] Next, an embodiment in which the present invention is embodied as an inkjet printer will be described with reference to the drawings. Moreover, in the following description, when referring to "front and rear directions", "left and right directions", and "up and down directions", they are respectively indicated in figure 1 The front and rear directions, left and right directions, and up and down directions indicated by arrow marks in .

[0032] Such as figure 1 As shown, an inkjet printer 11 as a recording device has a main body housing 12 . In the lower part of the main body frame 12, the support base 13 is extended along the left-right direction which is the longitudinal direction. On the support base 13, the recording paper P as a recording medium is conveyed in a direction (transportation direction; sub-scanning direction) from the rear side that becomes the upstream side toward The direction of the front side becomes the downstream side.

Abstract

A position adjustment mechanism is provided to adjust a position of second member with respect to a first member. The position adjustment mechanism includes: a cam that is provided in the first member so that a cam surface of the cam abuts the second member; and a fixing portion that is provided in a forming area of the cam surface in the first member and fixes the second member to the first member by screw in a state where the position of the second member with respect to the first member is adjusted by the cam.

Description

technical field [0001] The invention relates to a position adjustment mechanism and a recording device. Background technique [0002] In general, as a recording device that performs recording processing by adhering a liquid to a recording medium, there is widely known a printing apparatus that performs printing by ejecting ink (liquid) from each nozzle of a recording head mounted on a carriage to a recording medium. Ink printer (for example, Patent Document 1). In such a printer, in order to ensure printing accuracy, a structure is employed to adjust the position of the recording head relative to the carriage. That is, in the printer of Patent Document 1, there is a sliding contact member that is in sliding contact with the head unit (recording unit) to define the inclination angle of the head unit, and an adjusting eccentric cam that engages with the sliding contact member. By rotating the eccentric cam for adjustment, the inclination angle of the head unit is regulated v...
